Have you enabled Intel RST in the BIOS? Unless you (eventually) want to use RAID, you shouldn't enable it. It will cause this missing device problem and require you to jump through hoops to get around it. If you don't plan to use RAID, Intel RST offers you nothing (well, except complications).
If you do want to (eventually) use RAID, this will require the inclusion of the RST drivers -- which are very difficult to get ahold of as they do not make them available separately. In general, you should be going to the downloads page for your motherboard in the motherboard vendor's web site and getting the appropriate Intel RST installation package from there. I believe that you can open this executable in a ZIP tool (7-ZIP, for example) and extract the driver folders to insert into the Windows installer boot process. [Aside: I have to admit that I haven't tried this myself; I've just read about it in discussions here in the Community forums.]
Hope this helps,
